MACHINE FOR FLESHING, UNI-IAIRING, AND WORKING OUT HIDES AND SKINS.

To all 'whom it' 'may concern.'

Be it known that I, GEORGE W. BAKER, a citizen of the United States, resident of Vilmington, in the county of Newcastle and State of Delaware, have made a certain new and useful Invention in Machines for Fleshing, Unhairing, and l/Jorking Out Hides and Skins; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The invent-ion has relation to machines for fleshing, unhairing and working out hides and skins, embodying certain improvements upon the machine of my Patent Number 811,359, dated January 30, 1906; and it con` sists in the novel construction and combina` tions of parts as hereinafter set forth.

011e object of the invention is to provide means for fleshing a hide or skin as nearly clean as possible, with one passage thereof through the machine. Hides are always of more or less uneven thickness, bull hides being thin upon the back of the animal and thicker at the belly portion, while steers have hides of more even thickness, but slightly thinner at the belly portions. The fleshing is done in most cases after the hide is divided in two through the center, and it is these bull and steer hides that are designed to be cleaned by one passage thereof through the machine.

In the accompanying drawings, illustrating the invention, Figure 1 is a perspective view of my machine; F ig, 2 is an end view of the same; Fig. 3 is a similar view taken from the opposite end of the machine; Fig. 4 is a central vertical section of the upper part of the machine; Fig. 5 is a detail side view partly broken away of the latch mechanism and adjacent parts; Fig. 6 is a detail central longitudinal section of one of the connecting rods between the crank shaft and t-he bed roll; Fig. 7 is a detail central longit-udinal section of the spring connection between the upper feed roll and its driving pinion; Fig. 8 is a detail end view of the upper feed roll hub or end portion; Fig. 9 is a similar view of the pinion for this feed roll; Fig. 10 is a det-ail central longitudinal section of the clutch mechanism and adja- Speccaton of Letters Patent.

cent parts; Fig. 11 is a detail perspective view of the upright bed-roll and supportingroll carrying-arms at one end of the machine; Fig. 12 is a similar view of the vertical reciprocatory bars at the two ends of the machine, and F ig 13 is a detail side view of the1 gear connection between the two feed ro s.

In these drawings the numeral 1 designates the machine frame, having end standards 2, 2, longitudinally braced at 3. Upon these end standards are bolted the upper frames 4, 4, in which the cutter roll 5 is journaled, the frames 5a hinged to these upper frames carrying the feed rolls 6 and 7, and the rubber covered bed roll 3 having supports in movable arms to be hereinafter described.

Upon the end standards at the rear of the machine is journaled the longitudinal crank shaft 9, carrying a large spur gear wheel 10, arranged to operate in connection with suitable stopping and starting mechanism hereinafter referred to. Below the crank shaft is mounted upon the end standards a longitudinal shaft 11, carrying at one end thereof a large sprocket wheel 12, and at its opposite end a pinion 13, in mesh with the spur gear 10, said pinion having a clutch-toothed hub 14, arranged for engagement with a slidable clutch member 15, upon the same shaft.

machine, extending at right angles to the pinion shaft 11, is an arm 17, engaging the clutch member 15, and designed to make or release the clutch thereof with said pinion. A trip arm 18 is loosely mounted upon the shaft 1G, adjustment of the trip arm pivotally upon its shaft with relation to cams 19, 19, located diametrically opposite to each other upon the outer face of the spur wheel 10, being provided for by means of a sleeve 19a, fast upon said rock shaft, and carrying set screws 20, 20, located upon opposite sides of said trip arm, this adjustment being for the purpose of providing for such compensation as may be needed owing to wear of the cams. The trip arm has at its upper inturned end, an anti-friction roller 21, which bears upon one of the cams before the ma.- chine is started, and upon the opposite cam when the machine is brought to rest, said trip arm being thus thrown outward by the cams to operate the rock shaft and release Upon a rock shaft 16, at one end of the the pinion clutch, and being allowed to move toward the pinion to make the clutch.

For the purpose of keeping the slidable clutch member separated from the clutch hub o-f the pinion when the clutch is released, an arm 24 is carried by the rock shaft, a latch arm 25 having pivotal connection with the arm 24 at 26, and a depending projection 27, arranged to abut againstthe frame at 28, when the latch drops to rest upon the frame at 29.

The treadle 3l, has its carrying arm 32, mounted upon a rock shaft 33, and arm 33a fast upon said shaft and movable therewith, having at its rear end a pivotal connection at 34, with the lower end of an upwardly and rearwardly extending push arm 35, designed for operative engagement with pins 36, 36, located diametrically opposite upon the inner face of the spur gear 10, whereby when the treadle is depressed, this push arm will be caused to move upward and through its engagement with one of said pins to push the wheel l0 around suiiiciently to move the cam away from and out of engagement with the roller of the trip arm, which is thereupon thrown inward to make the clutch with the pinion, by means of a coiled spring 37, surrounding a bolt or rod 38, connecting the upper end of the arm 24 with the end standard. rlhe spur wheel 10 having been turned one half around, the opposite cam 19 will be brought into engagement with the roller of the trip arm, which will thereby be pressed outward against the tension of the spring 37 to release the pinion clutch,the opposite pin 36 at the same time moving into its seat 40 in the upper end of the push arm 35. l/Vhen the treadle is again depressed, the pinion clutch is again made and released in the same manner, each operation of the treadle allowing the spur wheel to turn 180 degrees. As the clutch is released, the movable clutch member will be slid to leave a small space between the two clutch members, when the latch drops automatically, and locks the clutch members apart until the treadle is again operated. Simultaneously with the depression of the treadle, the latch 25 is lifted to allow the pinion clutch to be made by engagement therewith of a vertical arm 41, pivoted to the arm 33 at 42. The latch lifter 4l has an upward extending rod connection 43, forming a rigid part thereof, and moving therewith,

` said rod carrying a counterweight 44,

whereby when the treadle is released, t-he counterweight will depress the latch lifter, and through its connection with the arm 33, restore the treadle to normal position.

The rubber covered bed roll is journaled in boxes 45, at the upper ends of long carrying arms 46, 46, located just without the standards at each end of the machine, and having at their lower ends pivotal connec- 'said carrying arms.

tion with short shafts 47, 47, the bed roll journals having extension through and movement forward and back within openings 48, 48, of the upper frames 4, 4, admitting of movement of the bed roll forward for placing the hide thereupon, and backward to cause the bed roll to press the hide against the cutter roll for fleshing purposes. The movement of these long carrying arms 46, 46, and of the bed roll is accomplished by means of connecting rods 49, 49, having at their rear ends pivotal connection with cranks 9a, 9a of the crank shaft, and at their forward ends pivotal connection 50 with Each arm 46 and its connecting rod are joined by means of a rod 52, having screw threaded engagement at one end thereof with the connecting rod and at its opposite end sliding engagement with a block 5l, said block having pivotal bearings in the arm 46 at 50, and said rod 52 being extended forward past the pivot block at 53, a strong coiled spring 54 surrounding the forward part of the rod and bearing at its rear end against the pivot block. Suitable nuts are provided upon the rod 52, to adjust the tension of the coiled spring, and the arms 46, being pivotally mounted at their lower ends, slight rearward movement of said arms and of the bed roll carried thereby against the tension of the coiled springs is allowed, to cushion the bed roll in its action against the cutter roll.

In order that the spur wheel l0 may be steadied when passing to its center or position of rest, when the crank and connecting rod are in line, and to prevent any creeping of the crank backward or forward of its position of rest, a friction band 22, has engagement with the clutch-toothed hub o-f the pinion, the ends of said band being made fastrto the frame at 23, and the band being capable of adjustment to vary the pressure thereof or to compensate for wear by means of a bolt 22L connecting the band ends, and having suitable adjustment nuts. This is particularly desirable as the strong coiled spring at the forward end of the connecting rod, in case said rod is not quite on center at the position of rest, would pull the crank to one side or the other, were it not for this friction check, when the pressure of the spring would be loosened, and the work imperfectly done.

For the purpose of throwing the bed roll out of parallel relation or at an angle to the cutter roll, when required for the right and left hand sides or halves of the hide, to make a tapered cut thereupon as before explained, a vertical reciprocatory bar 57,

. is provided at each end of the machine, said bar having sliding bearings in the frame at 58, and at its upper end a forward projection 59, upon which a set screw 60 having threaded engagement with a long bed roll carrying arm 46, has an end bearing. Thus when the bar 57 is moved endwise, the arm 46, at one end of the machine will be moved forward with the bed roll carried thereby, said bed roll moving in a substantially horizontal direction upon its opposite end as a center slightly away from the cutter roll, the journal bearings of the bed roll in the arms 46, 46, being sufficiently loose to allow the slight lateral movement of the journals in t-heir bearings required. In this waya slightly tapered interval is left between the bed roll and the cutter roll, which will cause a tapered cut to be made upon a hide of uneven thickness. Normally the bed roll and the cutter roll are in exactly parallel relation, for use with the skins of calves and with kips, or other small skins. which are not divided in halves, being of more even thickness. The set screw 60 at one end of the machine is normally located below and out of engagement with the projection of the sliding bar at such end, and the set screw 60a at the opposite end of the machine just above and out of engagement with the projection 59a of the sliding bar at this end, whereby an upward movement of the sliding bars, which work together, will throw the bed roll out at one end thereof, and a downward movement of the sliding bars will throw the bed roll out at its opposite end, according to the direction in which the tapered cut is to be made, for the right or the left hand half or side of the hide. This movement of the sliding bars is brought about by means of levers 6l, fulcrumed upon a shaft 62, said levers having each an inner arm 63 having at its rear end engagement with a perforation 64 of the sliding bar, a coiled spring 65 surrounding a reduced portion of the arm 63, and being located between the sliding bar and a shoulder 66 of said arm. The levers 6l, are provided with a cross handle connection 66a, which is thrown upward or downward by the workman according to the character of the cut to be made or the side of the hide to be operated upon.

The frame 5a at each end of the machine is hinged at its rear end to a longitudinal shaft 69, a boxing frame 7l at each end of the machine being pivoted upon the forward feed roll shaft, which is journaled in the hinged frames 5a, at the forward ends thereof, said boxing frames having journaled therein at the rear ends thereof the rear feed roll, and said hinged frames having at their forward ends a spring compression device 74, for pressing the feed rolls downward in a yielding manner against the bed roll, the boxing frames having at their rear ends each an adjustable pivotal rod connection 75, said rod having adjustment upward or downward by means of a lever 76, the hub 77 of which has threaded engagement with the upper end of each rod 75. Thus upon turning said lever', the rod will be moved endwise to vary the space or interval between the rear feed roll and the bed roll, this adjustment being secured by means of a nut or nuts 7 7a.

In order to prevent any central spring or give of the bed roll when under the strain of the fleshing process and to maintain the bed roll in proper operative relation at all parts thereof to the cutter roll, a supporting roll 90 is journaled in boxes 90a in the upper ends of long carrying arms 46a, 46a, located at each end of the machine just within the end standards and pivoted at their lower ends to the short shafts 47 aforesaid, upon which the arms 46 are also mounted, both pairs of carrying arms being oppositely located at each end of the machine and working in unison. rEhe bed roll is also provided wit-h journal bearings in the upper ends of the arms 46a, both pairs of arms moving together as stated, and the supporting roll being located in permanent contact with the lower portion of the bed roll throughout its length and moving therewith when the bed roll is thrown into and out of operative relation to the cutter roll. The boxes for the journals of the supporting roll are provided with a sliding adjustment in their seats to compensate for wear, set screws 901 being provided to fix this adjustment. For the purpose of preventing any upward spring or give centrally of the forward feed roll for the same reason, a central arc-form resistance block 91 has bearings in a central shallow annular groove 92 of this feed roll, the block 91 having a stem 93 seated at 94 in a longitudinal brace bar 94a connecting the hinged frames 5a, said stem having a set screw 95 bearing thereupon for purpose of adjustment. The top brace 94a connects and braces the hinged frames, and also provides a means of connection for the resistance block.

The upper or forward feed roll has a coiled spring 96 surrounding a hub 96a at one end thereof, said spring being fastened at one end to said hub at 96h and at its opposite end to the pinion 67 at 87, both said hub and said pinion having each a single lug, designated 98 and 99 respectively, and substantially three fourths of a revolution of the pinion being required before the two lugs are brought into engagement to rotate the bed roll through movement of said pinion, the coiled spring acting to return the hub and its lug to normal position. Thus as the pinion 86 upon the bed roll is turned by engagement therewith of the pinion S7 upon the feed roll when the machine is in operation, it is retarded by the spring` until the driver lug shall have made three quarters of al revolution, and then and not before the bed roll will begin to turn. In

this way the skin is not fed to the machine until it reaches the cutting cylinder, which is of particular advantage in fleshing small skins.

rthe large sprocket wheel 12 upon the pinion shaft ll has a chain connection with a small sprocket wheel 78 upon the shaft 69, which is the driving shaft for the feed rolls and the bed roll and is in constant rotation, this driving shaft having a pinion 8l in mesh with a large spur gear 82 upon the shaft of the upper feed roll, said shaft also carrying a small spur gear 83 in mesh with an intermediate spur gear Sel having driving engagement'with a small spur gear 85 upon the shaft of the lower or rear feed roll. W hen the bed roll is thrown rearward into operative relation to the cutter roll, the pinion 8G upon the bed roll shaft is brought into mesh with the pinion 87 upon the shaft of the upper or forward feed roll, to rotate the bed roll, which is retarded in its action as before stated. lvl/*hen the bed roll is thrown forward, this pinion engagement is released, and the bed roll is no longer turned. The cutterI roll shaft, which is also in constant rotation, is provided with a driving pulley 88, and a iiy wheel S9, which may form a part of the driving pulley, being so shown.

Having thus described my invention, what i claim as new and desire to secure by Letters latent is:
